modulation factor: In amplitude modulation, the ratio of the peak variation actually used, to the maximum design variation in a given type of modulation. When zero is reached, the modulation is considered 100%. ...

Is modulation factor the same as modulation index?

The modulation index is also called as modulation factor, modulation coefficient or degree of modulation. However, this modulation index is expressed as percentage and it is called as percentage modulation. Therefore, Here, m is a dimensionless quantity.

What is modulation factor on FM transmission?

The FM modulation index is equal to the ratio of the frequency deviation to the modulating frequency. ... As normal audio has a variety of different frequencies contained within the audio sound, the deviation ratio is normally calculated using the maximum audio frequency and maximum deviation.
